add_util: Defining utilities for events and interventions

In Roche/descem: Discrete Event Simulation for Cost-Effectiveness Modelling

Defining utilities for events and interventions

Description

Defining utilities for events and interventions

Usage

add_util(.data = NULL, util, evt, trt, cycle_l = NULL, cycle_starttime = 0)

Arguments

.data	Existing utility data
util	Value or expression to calculate the utility estimate
evt	Events for which this utility is applicable
trt	Interventions for which this utility is applicable
cycle_l	Cycle length; only needed if utilities are calculated per cycle
cycle_starttime	Cycle when utilities start being accrued; only needed if utilities are calculated per cycle

Details

Utilities can be defined by writing expressions and objects in the cost argument whose execution will be delayed until the model runs.

This function accepts the use of pipes (%>%) to define multiple utilities.

Value

A list of utilities

Examples

add_util(evt = c("start","idfs","ttot"),
trt = c("int", "noint"),
util = util.idfs.ontx * fl.idfs.ontx + util.idfs.offtx * (1-fl.idfs.ontx))
